Late last year, photos of Matthew McConaughey looking sickly hit tabloids. The actor had lost more than 30 pounds off his frame to star in the upcoming movie Dallas Buyers Club. Jared Leto also made headlines by dressing in drag for the same movie.

This week, the fruits of McConaughey’s crash diet can be glimpsed in the new official trailer for Dallas Buyers Club. The movie stars McConaughey as a Texan named Ron Woodroof who was diagnosed with HIV in the mid-80s. He and “Rayon” (played by Leto) band together with other HIV-positive people create a club to import unapproved HIV medications into the U.S.

The movie has a December 6 release date in the U.S., but will also be screened at the Toronto Film Festival next month.
